The Science of Hair Growth
Happy Science Sunday! Let's talk hair growth!
Our hair isn't just there to look pretty (though it can definitely do that too!), it's constantly growing and changing. Today, we're diving into the science behind what makes our hair grow.
Hair has a life cycle with 3 phases:
Growth phase (Anagen): This is where the magic happens! Hair actively grows from the root for years (2-6 to be exact). This phase determines how long your hair can get.
Transition phase (Catagen): This short phase (about 2 weeks) is like a mini-retirement for your hair. The hair follicle starts to shrink and gets ready to rest.
Resting phase (Telogen): The hair basically chills for a few months (around 3) before falling out. Then, a new hair starts growing in its place, and the whole cycle begins again!
Genes play a big role in your hair:
They decide things like hair color, texture (straight, wavy, curly), and how thick your hair is.
Genes also influence how long the growth phase lasts, which affects how long your hair can grow.
Hair can also be affected by aging, thanks to genes. Some people see thinning or hair loss earlier than others.
Other things that affect your hair:
Food: Not eating the right things can lead to hair loss or slow growth. Make sure you're getting enough vitamins and minerals!
Stress: Feeling stressed can push more hair into the resting phase, causing shedding.
Hormones: Changes in hormones, like during pregnancy or menopause, can affect hair growth.
Environment: Sun and pollution can damage hair and mess with its growth cycle.
The good news? You can help your hair grow strong and healthy!
Eat a balanced diet to give your hair the nutrients it needs.
Manage stress – less stress, less hair loss!
Protect your hair from the sun and harsh chemicals.
Taking pills meant for hair growth can take 2-4 years before you notice anything. 🙃
By understanding hair science, you can take charge of your hair care routine. Remember, healthy hair starts from the inside out! So let's keep those roots (both literal and metaphorical) happy and have a good hair day, every day!
Stay tuned for next Science Sunday! Until then, keep learning and keep those curls (or waves, or straight locks) shining!
